Summary
In unincorporated Palm Beach County, a fence or wall built along a retaining wall on a Single Family lot can gain extra height matching the grade change next door: up to six feet in a front setback and eight feet in a side or rear setback.
The height of a fence or wall located within the front, side, or rear setback of a lot supporting a Single Family dwelling unit, may be increased when located adjacent to a lot having a different elevation where a retaining wall is installed along the property line... The height of the fence or wall may be increased by the difference in grade up to a maximum of two feet, whichever is less, as follows: (1) Within the required front setback: Up to a maximum of six feet. (2) Within a side or rear setback: Up to a maximum of eight feet.
Full Breakdown
The ULDC caps a residential fence or wall at four feet in the required front setback and six feet in the side, side-street, or rear setback. Where that fence or wall sits on a retaining wall along a property line with a different grade than the neighboring lot, Palm Beach County's Planning, Zoning and Building Department lets the height climb by the elevation difference, capped at two additional feet: a maximum of six feet in the front setback and eight feet in a side or rear setback. Where the grade difference exceeds two feet, a guard railing up to three feet tall is allowed above that, but only if it meets the code's opening and strength requirements.
Violations & Fines
A fence or wall exceeding these height caps, or a retaining-wall height increase claimed without a documented grade difference, is a Building Permit and code compliance violation; Palm Beach County can order the structure altered or removed.
